Please, test with a small sample of your given directory.

It creates a file.bk from the file that it finds in the directory, for safety reasons. If the result in the file.bk is correct, remove the
last commented command to rename the backup to the original name and run in the production/real directory

Run as:
Code:
perl kylle345_run.pl /path/to/directory/*.txt

Code:
#!/usr/bin/perl
# kylle345_run.pl

use strict;
use warnings;
use File::Copy qw(move);

# process each file given at the command line
for my $fname (@ARGV){
    my $fh;
    # open the current file    
    if(not open $fh, '<', $fname){
        # file could not be read; skip
        print STDERR "$fname could not be processed\n";
        next;
    }
    print "Processing file: $fname ...\n";

    # obtain substrings from file name if not skip
    my @names = $fname =~ /\[(.+?)\]\[\w\]/g or next;
    open my $fh_bk, '>', "$fname.bk" or next;
    my $before_last = "AMEL\tX\tY\t\tX\tX\n";

    # read the current file
    while(<$fh>){
         # only at second line substitute the xxx.fsa with parts of filename
         s/\w{3}\.fsa(\s+)\w{3}\.fsa/$names[0]$1$names[1]/ if $. == 2;
         # add a line before last
         if(eof) {
             print $fh_bk "$before_last$_";
             next;
         }
         # write to a copy ending in .bk
         print $fh_bk $_;
    }
    close $fh;
    close $fh_bk;
    # test first and if it does correctly, remove the
    # # from next line to rename backup to original name
    #move "$fname.bk", $fname;
}

rmf

rmf(1)							      General Commands Manual							    rmf(1)

NAME

       rmf - remove folder (only available within the message handling system, mh)

SYNOPSIS

       rmf [+folder] [-help] [-[no]interactive]

OPTIONS

       Prints  a  list of the valid options to this command.  Asks for confirmation before deleting a folder. By default, rmf deletes a folder and
       its messages without asking for confirmation.  If you specify the -interactive option, rmf asks if you are sure before deleting the folder.
       You are advised to use this option, since when rmf deletes a folder its contents are lost irretrievably.

DESCRIPTION

       The  rmf  command  removes all of the messages within the current folder, and then removes the folder itself. If there are any files within
       the folder which are not part of MH, they are not removed, and an error message is displayed.

       You can specify a folder other than the current folder by using the +folder argument. If you do not specify a folder, and rmf  cannot  find
       the current folder,rmf asks you whether you want to delete +inbox instead.

       If the current folder is removed, it makes +inbox current.

       Note that the rmf command irreversibly deletes messages that do not have other links, so use it with caution.

       If  the	folder	being removed is a sub-folder, the parent folder becomes the new current folder, and rmf tells you that this has happened.
       This provides an easy mechanism for selecting a set of messages, operating on the list, then removing the list and returning to the current
       folder from which the list was extracted.

       Using  rmf  to  delete a read-only folder deletes the private sequence and current message information from the file, without affecting the
       folder itself. If you have sub-folders within a folder, you must delete all the sub-folders before you can delete the folder itself.

PROFILE COMPONENTS

       Path: To determine the user's Mail directory

EXAMPLES

       This example shows how rmf asks for confirmation when the -interactive option is used: % rmf -interactive +test Remove folder "test"? y

FILES

       The user profile.
